It also provides PV power plants and supporting services that include finance, construction, maintenance and panel recycling. The company is quite popular among traders and investors alike. It trends very well with smooth fluctuations in the larger trading channels, and it has a reputation for explosive moves with entry triggers that appear at relatively reasonable price points. Shares of First Solar have fallen in and out of favor quite often in recent months. After soaring in April to establish a third wave of buying on the weekly time frame, the shares began to pull back and correct over the summer months. Slowing momentum into May's highs helped fuel that corrective move. By the end of June, First Solar had given back about 50% of the gains it had made during the second-quarter rally. Shareholders' disappointment continued as the correction unfolded. The strong price support at the midsummer lows resulted in a rally into July, but the momentum of that upside was still more gradual as a whole than the prior drop. This eventually led to a second major pullback on the weekly time frame throughout August.
